I propose the following methods Array#ljust(length [, pad]), Array#rjust(length [, pad]), whose behaviour is analogous to String#ljust(length [, padstr]), String#rjust(length [, padstr]).

    [:a, :b, :c].ljust(2) #=> [:a, :b, :c]
    [:a, :b, :c].ljust(5) #=> [:a, :b, :c, nil, nil]
    [:a, :b, :c].ljust(5, :x) #=> [:a, :b, :c, :x, :x]
